HEAT-RADIATOR.-

SPEGIFICATION forming part of Letters Patent No. 628,689, dated July 11, 1899. Application filed September 16, 1898. Serial No. 691,097. on model.)

T0 all whom it may'concern:

Be it known that 1, MICHAEL MARY BRO- PHY, a subject of the Queen of GreatBritain, residing at London, England, have invented new and useful Improvements in Heat-Radiators, (for which I have applied for a patent in Great Britain, No. 14,297, dated June 28, 1898,) of which the following is a specification.

My invention relates to heat-radiators of the kind wherein hinged leaves or coils are employed for facilitating cleaning, the objects of the present invention being to simplify the construction of such apparatus and increase the facility with which access to the various parts can be obtained.

According to my present invention instead of hinging the leaves upon a post or upright which formed no part of the heating system I now hinge them upon a post which forms a part of the return-pipe through which the water or steam flows after having passed through the heating coil or coils. I also provide novel arrangements for' forming the joints at the hinges of the several leaves and forpreventing steam or water from entering a leaf or leaves from the return-pipe.

To enable my invention to be fully understood, I will describe the same by reference to the accompanying drawings, in which- Figure 1 is a sectional side elevation of an apparatus provided with a single movable leaf or coil; and Fig. 1 represents a horizontal section through the lower bracket for supporting the movable leaf or coil, showingsaid bracket arranged to receive a return-pipe above the floor. Fig. 2 is a section on the line 2 2, Fig. 1. Fig. 3 is a plan view illustrating the arrangement of a radiator having a series of leaves or coils.

Cb is the hanging post or pillar, which is adapted to be securely fixed to the fioorof the building or apartment in which the radiator is to be fixed and which in the case of hospitals or other buildings having concrete, stone, or like floors is advantageously formed at the lower end as shown in Fig. 1,. so that it may be embedded in the floor, but which may be otherwise formed and fixed. This pillar is made hollow and adapted to have connected to it either at the lower or upper end, or at both ends, the return-pipe a for the water or steam.

Then the return-pipe serves also for a coil upon a fioor above, I advantageously arrange that the pipe shall be connected with the pillar at the upper end by an expansion-joint. The form of expansion-joint which I advantageously make use of is'shown at b in Fig. 1. This joint comprises the spigot end 0, adapted to slide in a socket d in the upper end of the pillar a, and a packing-gland e, which serves to compress a ringfof packing in a groove formed partly in the gland itself and partly in a screw-cap g (hereinafter described) on the upper end of the pillar.

h t' are two brackets which are bored out to fit correspondingly-tnrned portions on the pillar a, the said brackets having in the portions which project from the pillar sockets for receiving the hinge-terminals of the leaf. In the turned portion of the pillar upon which the bracket his fitted a hole j is formed, and the bracket h is formed with a channel It and with the inlet-passage Z. By thus arranging a channel It in the said bracket it through communication between the passage land the interior of the pillar through the opening or openingsj always exists, no matter what may be therelative positions of the bracket and the said pillar. In cases where the return-pipe instead of extending through the floor, as shown in Fig. 1, is to be carried above the floor I form the said bracket 72. with a socket h, as shown in Fig. 1, to which the return-pipe can be connected, If desired, the channel 7.: (shown in Fig. 1) can be dispensed with if the passage Z and the holes in the pillar are made to correspond.

m m are packing-rings, and n is a nut screwed onto the pillar, the said nut serving for retaining the bracket in its proper position upon the pillar and also for compressing the packing-rings to form a tight joint for preventing the escape of water or steam. The

upper bracket 11 is held in position by the screw-cap g hereinbefore referred to, a packing-ring g being arranged between the said ring and the top of the bracket for preventing leakage. i

0 is a hinged leaf provided with a series of heating-pipes p p, fixed at their ends to the castings q which for convenience of de-' scription I will term junction-pipes. The junction-pipe g has a series of apertures, into which the pipes 19 p are fixed by means of a tube-expander inserted through holes in the back of the said junction-pipe, which holes are ultimately closed by plugs s s, and the.

junction-pipe r is provided with a series of nozzles, upon whichthe tubes are fitted, as

ing leakage between the bush and the said.

junction-tube. The upper end of the junction-tube is constructed in a similar manner to the lower end and is provided with a collar u, having a groove similar to the flange or collar and groove 75 t the exterior of the flange or collar to fitting in the lower end of the socket in the upper bracket 1.

Over the upper end of the junction-pipe q i is fitted a cap '2), the lower end of which rests upon packing material in the groove a, while the upper end of the said cap is formed with an aperture, to which the flow-pipe w for the steam or water is fitted, as shown in the drawings. This pipe wis provided with an expansion-joint to similar to the expansionjoint I) hereinbefore described. *Around the cap '0 is a screw-collar 1;, which is inserted into the upper end of the socket of the bracket 1 and presses against a spring 41 which at its lower end bears against a shoulder on the cap 1 and serves to press the lower end of the said cap against the packing in the groove u to form a tight joint around the upper end of the junction-tube g. This arrangement for hinging the leaf 0 permits of the latter being turned in any direction in order to afford access to all.the parts for cleaning the same.

In practice the packing material in the groove i a has placed upon it a thin metallic washer for the purpose of preventing the packing being unnecessarily worn when the leaf is moved.

With the apparatus hereinbetore described the steam or hot water enters the coil through the pipe w, whence it flows from the upper part of the junction-pipe q (the said pipe having in it a partition, as indicated at m in Fig. l) and the pipes 19 29, connected therewith, into the junction-pipe r and thence through the lower tubes 19 back to the junction-pipe q, whence it flows through the passage Z, channel 7t, and openingsjj to'the interior of the pillar a and to the return-pipe.

A suitable valve is provided in connection with the flow-pipe w for shutting off the supply of heating fluid when required. In order that when the fluid is so shut off the steam or hot water from the return-pipe shall not flow back into the coil through the passage Z, I arrange in connection with the lower end of the junction-pipe q a valve ;1 which is normally pressed against its seat by a spring y, the said spring being sufficiently light to allow the valve to open under the actionof the fluid entering through the flow-pipe w. The valve y, as shown, is carried upon a stud 3 on a plug 31 which is inserted into the lower end of the socket of the bracket h.

z is a supporting-wheel which when my invention is applied to heavy coils serves to facilitate the movement of the same and to relievev the joints of any unnecessary strain, and z is a cock for allowing the escape of air from the pipes. I

Then two or more leaves or coilsare to be arranged to form a radiator, the brackets h and t' are each provided with a number of sockets corresponding with the number of coils to be employed. In fixing thesebrackets they are preferably arranged at such an anglefor instance, as shown in Fig. 3-that each leaf can be turned back to a position, say, at right angles to the wall against which the radiator is placedthat is to say, from the position shown in full lines incthe said figure to the position indicated by the dotted lines. The arrangement of the channel It within the lower bracket h readily permits of this adjustment of the bracket without interfering with the water-passages.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In a radiator, the combination with a vertically-disposed stationary hollow pillar, of laterally-extending brackets secured thereto, adjacent to the upper and lower ends of said pillar, and a radiator wing orsection, pivotally mounted in said brackets and communicating with the interior of the pillar, substantially as described.
